c) State of the art

Driving rod gearboxes of this type are known. Heard like that it for example by the DT-OS 20 26 368 to the prior art, on the back of the faceplate between this and the drive rod slidably guided thereon has a swivel arm designed as a two-armed lever on one with the To arrange forend rail firmly riveted bearing journals. There is a spring element that is designed as a two-armed lever Swivel arm each with the two free ends in the movement path of cams rigidly attached to the drive rod as soon as the sash of the window or door is brought into an open position. At the free ends of the two lever arms are located transversely to the plane of movement of the swivel arm pegs that protrude through transverse slots in the faceplate and with a stop plate arranged on the stationary frame come into operative connection when the sash is moved to the closed position. The swivel arm is counteracted via the pin the spring force from the movement path of the locking cams seated on the drive rod, so that the drive rod move lets when the rotary drive member mounted in the gear housing is moved by the operating handle.

In this known espagnolette edge drive, the incorrect operation lock is already fully integrated during manufacture, that is, the espagnolette edge gear is basically equipped with a mishandling device, so that there is always a double-track Manufacturing and warehousing becomes necessary, though

Espagnolette edge drive without a mishandling device are required.

A drive rod edge drive is also known from CII-I ⁵ S 324 607, which has a similarly constructed incorrect operation lock. liier, however, the pivot arm mounted on the back of the faceplate is designed as a one-armed lever, which interacts with a stop on the frame side via an angled section at its free end that is parallel to the faceplate plane of the wing profile.

In this case too, however, two-pronged production and storage is necessary if, in addition to connecting rod edge drives With a mishandling device, those without a built-in mishandling device must also be available.

To avoid these circumstances, the DT-AS 12 73 365 already includes the state of the art, one with a to accommodate spring-loaded swivel arm operating mishandling device in a special housing and this only as needed to be coupled with the drive rod of an edge gear instead of a normal tenon closer.

d) Description of the innovation i

The purpose of the innovation is to address the shortcomings of all of the above

to eliminate the wrong operation locks described. It is therefore the task of the innovation to create a connecting rod edge

gear of the type explained at the beginning to create which?

at any time - even afterwards - if necessary with an incorrect |

can equip service lock. \

According to the innovation, the solution to this problem is essentially

achieved in that the faceplate and / or the gear housing firmly connected to it with H old gripped for the releasable fastening of the bearing bolt carrying the pivot arm and a support member for the spring element is provided.

Since the locking member interacting with the locking notches of the swivel arm is connected to the drive rod from the start can be without it appearing disruptive, an incorrect operation lock according to the invention can be in a simple manner Provide depending on requirements or not.

According to the innovation, an important further training feature is seen in the fact that the spring element consists of a leg spring Band material is received together with its support member in recesses provided on the rear of the swivel arm is.

On the other hand, it has to pursue the idea of innovation turned out to be particularly useful to form the retaining engagement for the bearing pin as a thread and in the faceplate to be provided, while the holding engagement for the support member of the Fc-derelementes from a polygonal cutout in a die Forend rail overlapping flange of the gear housing is made.

Another important measure of the innovation is that the spring element with a polygonal eye can be turned 180 and can be switched on the correspondingly profiled support member and the support member in turn has a through hole for the shaft of the as

Has pan head screw shaped bearing pin. Here, the support member can screw as a screw-in limiter for the flat head has been clamped between the faceplate and the screw head, and the head of the flat head screw can be used as a Engage the bearing element in a recess on the swivel arm.

So that the incorrect operation lock can be installed easily for right or left stop as required, is according to the innovation it is also provided that the retaining engagements are arranged on the longitudinal center line of the faceplate and the gear housing and the swivel arm is designed symmetrically to its longitudinal center plane.

From a structural point of view, according to the innovation, it is on the one hand possible to design the locking member seated on the drive rod as a flat pin protruding through a longitudinal slot in the faceplate, which is provided in a slot on the rear side, which is provided with lateral extensions that serve as locking stops at certain points of the swivel arm protrudes. This flat pin can be made so short that it can be used even if there is no mishandling is installed, cannot interfere with the function.

On the other hand, however, it has proven to be particularly advantageous when the locking member sitting on the drive rod consists of cams located below the faceplate and the counter-locking from the rear is formed in the pivot arm attached projections, the can be adjusted in the path of movement of the cams through transverse slots in the faceplate.

From Fig. 1 it can also be seen that the face plate 1 in its adjoining the gear housing 3 area Has longitudinal slot 8, from which a flat pin 9 protrudes by a certain amount, which is fixed to the drive rod 2 is riveted.

If the drive rod is formed by moving the pinion 4 Rotary drive member moved by means of an operating handle, then the flat pin 9 makes the corresponding Sliding movement in the longitudinal slot 8 with. It can be used as a locking member for one with the espagnolette bevel gear Bringable mishandling device can be used.

As can be seen in particular in FIGS. 2, 6 and 7, this mishandling device has a swivel arm 10 which is designed as a one-armed lever and can be releasably mounted on the drive rod edge gear by means of a bolt 11 designed as a flat head screw.

For bearing the pivot arm 10 on the drive rod edge gear, the bolt 11 designed as a flat head screw is also included its threaded shaft 12 'into the threaded hole forming the retaining engagement G. the faceplate-1 screwed in. The flat head 12 '' of the bearing pin 11 engages in an adapted bearing recess 13 on the end face of the pivot arm 10.

On the threaded shaft 12 'of the bearing pin 11 is a in cross section rectangular, with a central through hole 14

equipped support member 15 attached, which with his one End is fixed in a rotationally fixed manner in the retaining engagement 7 of the gear housing 3 and the other end of which is a support for the flat head 12 of the bearing pin 11 forms.

The outer periphery of the support member 15 is defined by one of its outline shape adapted eye 16 of a leg spring 17 made of strip material, the free leg 18 of which engages in a rear recess 19 of the swivel arm 10. The recess 19 on the back of the pivot arm 10 is special can be clearly seen from FIGS. 6 and 7. It also results that the swivel arm 10 is symmetrical to its longitudinal center line is designed and has a recess 19 on both sides of the same. Depending on which of these two recesses the free leg 18 of the leg spring 17 is brought into engagement by appropriately plugging it onto the support member 15, the leg spring 17 seeks the pivot arm 10 either to one side or to the other side from its parallel position to

I Forend rail 1 to swivel out the bearing pin 11. |

As can be seen particularly clearly from FIG. 6, the swivel arm 10 has on its rear side a lying on its longitudinal center plane Link slot 20, within which, when the swivel arm 10 is parallel to the faceplate 1, the connecting rod 2 is connected and from the longitudinal slot 8 of the faceplate 1 protruding flat pin 9 can be moved.

This link slot 20 is on both sides at predetermined points

provided with extensions 21 and 22, respectively, in such a way that the flat pin'9 in two predetermined sliding positions of the drive rod 2 within the link slot 20 in the area of this Extensions 21 and 22 come to rest.

Under the action of the leg spring 17, the pivot arm 10 can move from its parallel position to the faceplate 1 around the bearing pin get into an inclined position so that the flat pin 9 arrives in one of the enlargements 21 or 22 adjacent to it, these form a locking stop against displacement of the flat pin 9 and thus the drive rod 2.

The swivel arm 10 moves into this locked position when the wing is opened and, as a result, the swivel arm 10 comes out of contact with the stop plate 23 sitting on the stationary frame. However, the wing will again closed, then the stop plate 23 pushes the swivel arm 10 back into its parallel position to the faceplate 1 whereupon the the locking stop forming extensions 21 and 22 of the link slot 20 release the flat pin 9 and thus a shift the connecting rod 2 enable. The various pivot positions of the pivot arm 10 are indicated in FIG. 5. The fully undressed Lines show the parallel position of the swivel arm 10 to the everting rail 1. The swiveled-out position is indicated by dash-dotted lines of the swivel arm 10 indicated at the right stop of the espagnolette edge gear, while the dashed lines indicate the swiveling position of the swivel arm 10 indicate left stop of the espagnolette bevel gear.

In Fig. 7 the individual parts of a mishandling device are shown, the one compared to the embodiment according to the! "" ig. 2 to 6 have modified design.

In this mishandling device, the drive rod 2 is each with a flat pin 29 'on both sides of its longitudinal center plane. Mistake. These flat pegs 29 'can be displaced below the faceplate 1 together with the drive rod 2.

The swivel arm 30 is at the rear instead of with a link slot having extensions with two spaced apart one behind the other lying projections 31 and 32 and the faceplate 2 has instead of the longitudinal slot 8 two transverse slots 28 'and 28 "on.

If the swivel arm 30 is attached to the drive rod edge drive in the manner shown in particular in FIGS. 2 and 3, then its projections 31 and 32 engage through the two transverse slots 28 'and 28 "of the faceplate into the range of motion of the two flat pins 29' of the drive rod 2. In the Closed position of the window or door sash, that is, when the pivot arm 30 against the force of the leg spring 17 by the Release stop 23 is placed in parallel position to faceplate 1, The flat pegs 29 'of the drive rod can move past the rear projections 31 and 32 of the pivot arm 30 unhindered. If, on the other hand, the wing is open, the rear projections 31 and 32 of the pivot arm 30 are activated by the leg spring 17 laterally in the path of movement of one of the two flat pins 29 '

and the sliding movement of the connecting rod 2 is blocked via this.

The advantage of the configuration shown in FIG results, lies in the fact that, apart from the locking pin of the connecting rod edge gear, none can be moved with the connecting rod Parts protrude over the face of the faceplate 1. The transverse slots 28 'and 28 "in the faceplate can be In addition, if no mishandling device is installed, by means of an adhesive film or clipped-in plastic molded parts close so that dirt and paint cannot penetrate there.

g) The commercial area of use

The drive rod edge drives described can be used in connection with windows and doors of all types. In particular they can be used for windows and doors whose sash is hinged as a turn-tilt sash and where the different functional positions can be switched from a central operating handle.

It is, of course, also possible to disable the incorrect operation to be attached to the espagnolette drive during manufacture.
